Free SSL certs to acamdemic sites

Hi All,
does anyone have any experience with
http://certs.ipsca.com <http://certs.ipsca.com> who claim to offer free
certificates to academic sites? I could find no information on their
website about browser support and I suspect it is minimal or nonexistent
but I'd be very happy to be proved wrong.
I've sent email to see what they say.
